你好。我叫茉莉。我学了中文差不多二（两 we use different number characters when counting objects）年半。我的中文还不是很好。我去年我开始认真上中文课。我试着读很多中文的漫画和中文的书。我的朋友也有帮助我练习对话。

My family

Today, I will introduce my family. We are a family of five, and includes my father, mother, older sister, my brother, and me. (There are five in my family.)
My father is not frank. He was a police officer, but he retired three years ago and now works as a security guard.
My mother is very clumsy, but she is always thinking of my family and works hard for us. She is a housewife and sometimes works at a part time job. Moreover, she can use sign language and has a qualification for making bread. wow
Finally, My sister was a English teacher, but she retired because she had a baby at the time. she now works as an office worker. Her son or my nephew is 7 years old and in second grade of elementary school. He's just a naughty boy.

We went on several family trips when I was a child, but now not at all because I'm busy with my research in college. I hope I will get to travel with my family again.

How about your family. Do you get along with your family??

Thank you for reading. Could you correct my sentences? Are there any other ways to say this? If you'd like, please teach me. Thanks.
